Yuta Hibiki wakes up in the home of his classmate, Rikka Takarada, with amnesia. A voice from an old computer, identifying himself as "Gridman," has a mission for him, but can he even survive the next day of school without his memories?
Hibiki, are you the "stiff-upper-lip-
even-when-hungry samurai" type?
Hibiki, auch ein Krieger, der nichts
im Magen hat, kann herzhaft lachen!
Hibiki,
Hibiki, « un guerrier rigole fort
de son repas manqué »,
Hibiki, você é do tipo que não
demostra nem quando está com fome, né?
